Requirements and architecture specifications are strongly related as the second provides a solution to a problem stated by the first. This coupling is typically realized by traceability links and maintaining such links becomes extremely difficult as both requirements and architecture specifications frequently evolve, and in particular when the architecture is refined providing an increasing level...
Good requirements engineering practices are essentialfor developing correct safety-critical systems. In this paper, we report our experience in combining existing rich modelinglanguages such as AADL (Architecture Analysis and DesignLanguage), URN (User Requirements Notation) and RDAL(Requirements Definition and Analysis Language) to supporta requirements engineering and design process as promotedby...
